The present invention relates to a toy gun and, more particularly, to a hydro-blaster toy gun ballistic backspin control structure.
A toy gun is used to fire a BB shot that is a spherical projectile. However, the driving power is too large whether it is a pneumatic toy gun or an electric toy gun, so that the BB shot easily causes a danger. Therefore, hydrogel material is used to form the BB shot which is generally called a hydrogel ball or water bullet or gel bead or hydro-blaster.
The water bullet is cheaper than a plastic bullet or a paint bullet and is also portable (it can be stored in a plastic bottle or plastic bag at a dry state, and can be used after soaking in water for a few hours before use). The water bullet is almost composed of water molecules. When the water bullet hits the target, the residues will become a fine powder that decomposes naturally after the water evaporates so that the water bullet will not cause an environmental pollution.
However, the water bullet is very fragile, and will be broken in the gun once the chamber pressure is too high. Therefore, the water bullet cannot be pushed into the gun chamber by a spring pressure like a plastic bullet. Thus, a bullet feeder is used to deliver the water bullet into the gun chamber by the gravity. Alternatively, the industry has developed a lower magazine with a built-in motor. It is powered by the battery of the gun body through the contact point, and a gear is driven to push the water bullet into the bullet supply tube and into the gun. However, this kind of motor structure is too complicated, and it is easier to accidentally break the water bullet, thereby causing problems such as a short circuit and an electric leakage. In addition, after the water bullet breaks, the gel is dried and causes problems such as gear jamming.
A conventional hydro-blaster gun backspin device was disclosed in the Chinese patent application Ser. No. 202021127343.1 (publication No. CN 213120277 U). However, such a backspin device has the following disadvantages.
After the water bullet continuously contacts the friction lines, the surface will actually wear a lot. Although the water bullet is made of a gel substance, the water bullet will break away from the friction plate after a short period of continuous friction. The volume at the time must actually be smaller than the volume before entering the friction plate, so the friction between the water bullet and the friction plate will become smaller and smaller (according to the moving route of the water bullet), and the directional rotation speed of the water bullet will also decrease.
At the same time, the water bullet is in continuous contact with the friction patterns of the friction plate. Therefore, the water bullet itself has two kinds of kinetic energy, including the kinetic energy of displacement towards the muzzle direction, and the kinetic energy of directional rotation. After the kinetic energy of the displacement of the water bullet comes into contact with the friction lines, in addition to the kinetic energy of directional rotation, the kinetic energy of the displacement will be continuously consumed during the friction process. The surface of the water bullet contains water, which cannot be provided by the friction lines alone. The friction makes the water bullet unable to effectively increase the directional rotation speed, and will consume most of the kinetic energy.
The primary advantage of the present invention is to provide a hydro-blaster toy gun ballistic backspin control structure that adjusts the pressing force applied on the water bullet in a stepless regulating manner.
The secondary advantage of the present invention is to provide a hydro-blaster toy gun ballistic backspin control structure that increases the backspin rate of the water bullet.
In accordance with the present invention, there is provided a hydro-blaster toy gun ballistic backspin control structure comprising a backspin bullet tube and an elastic adjusting piece mounted in the backspin bullet tube. The backspin bullet tube has an interior provided with a passage extending therethrough. The backspin bullet tube has a first end provided with a connecting portion connected with a barrel. The backspin bullet tube has a second end provided with a bullet outlet. The passage is provided with a positioning recess. The passage is provided with two slideways arranged symmetrically. The elastic adjusting piece has an arcuate shape. The elastic adjusting piece is mounted in the passage of the backspin bullet tube. The elastic adjusting piece has a top provided with a positioning portion fitted into the positioning recess. The elastic adjusting piece is provided with two side wings fitted into the two slideways respectively. The elastic adjusting piece is provided with multiple grooves. The grooves divide a bottom face of the elastic adjusting piece into multiple friction sections. A water bullet enters the backspin bullet tube through the connecting portion and contacts the elastic adjusting piece. The water bullet contacts the friction sections and produces a friction force. When the water bullet leaves one of the friction sections and enters one of the grooves, the water bullet is forced by the friction force between the water bullet and one of the friction sections and produces a respective backspin rate which produces a centrifugal force which forces partial water of the water bullet outward through one of the grooves. when the water bullet leaves the friction sections and enters the grooves, the water bullet is forced by the friction force between the water bullet and the friction sections and produces backspin rates which produce centrifugal forces which force water of the water bullet outward through the grooves so that the hydro-blaster toy gun ballistic backspin control structure adjusts the backspin rates of the water bullet in a stepless regulating manner.
Referring to the drawings and initially to
The backspin bullet tube 1 has an interior provided with a passage 11 extending therethrough. The backspin bullet tube 1 has a first end provided with a connecting portion 12 connected with a barrel 3. The backspin bullet tube 1 has a second end provided with a bullet outlet 13. The passage 11 is provided with a positioning recess 14. The passage 11 is provided with two slideways 15 arranged symmetrically.
The elastic adjusting piece 2 has an arcuate shape in radial cross-section. The elastic adjusting piece 2 is mounted in the passage 11 of the backspin bullet tube 1. The elastic adjusting piece 2 has a top provided with a positioning portion 21 fitted into the positioning recess 14. The elastic adjusting piece 2 is provided with two side wings 22 fitted into the two slideways 15 respectively. The elastic adjusting piece 2 is provided with multiple grooves 23. The grooves 23 divide a bottom face of the elastic adjusting piece 2 into multiple friction sections 24.
In practice, a water bullet (or hydrogel ball or gel bead) enters the backspin bullet tube 1 through the connecting portion 12 and contacts the elastic adjusting piece 2. The water bullet contacts the friction sections 24 and produces a friction force. When the water bullet leaves one of the friction sections 24 and enters one of the grooves 23, the water bullet is forced by the friction force between the water bullet and one of the friction sections 24 and produces a respective backspin rate (or velocity) which produces a centrifugal force which drives (or forces or turns or swings or shakes or throws) partial water of the water bullet outward through one of the grooves 23. Thus, when the water bullet leaves the friction sections 24 and enters the grooves 23, the water bullet is forced by the friction force between the water bullet and the friction sections 24 and produces backspin rates which produce centrifugal forces which drive water of the water bullet outward through the grooves 23 so that the hydro-blaster toy gun ballistic backspin control structure adjusts the backspin rates of the water bullet in a stepless regulating manner.
It is appreciated that, the water bullet is rotated upward when moving forward due to the friction force between the water bullet and the friction sections 24 and produces a backspin rate which causes a Magnus effect so that the water bullet flies in the air during a long period of time to increase the distance of travel.

The positioning portion 21 of the elastic adjusting piece 2 is slidably inserted into the positioning recess 14. The two side wings 22 of the elastic adjusting piece 2 slide into the two slideways 15 respectively. Each of the two side wings 22 of the elastic adjusting piece 2 rests on the horizontal top 151 of one of the two slideways 15. The adjusting member 17 is inserted through the adjusting hole 16 into the backspin bullet tube 1 and presses the positioning portion 21 to position the elastic adjusting piece 2 in the backspin bullet tube 1.
